Lightweight and durable

JBL, one of the leaders in live sound reproduction, brings you their EON 315 powered loudspeaker so you can better present your music to your audience. This speaker's rugged and lightweight molded enclosure is made of a non-resonant composite polymer that'll survive most on-the-road mishaps. It protects the speaker system so it will successfully play the gig every time — and sound great doing it. It also really helps that, at the end of a long, tiring night, this powered PA speaker weighs only 35 pounds and fits easily in most backseats or trunks.

Built-in electronics

Each EON 315 is a one-piece 560-watt PA system, featuring a 15" woofer, a 1" high-frequency compression driver, built-in Class D power, and a 3-channel mixer. A line input lets you play music from most sources while a microphone input allows you set up an EON 315 as a PA speaker for a conference or for a performance in a small auditorium.

Gain control and a couple of EQ settings let you adjust the sound to blend perfectly. Other onboard electronics include a 2-way crossover, two Class D power amplifiers, and a dynamic limiter all matched and designed to work together to play your music flawlessly and keep the components safe from overload and damage.

Loud enough for venues small and large

The efficient EON 315 can turn its 560 watts of power into 127 dB of sound pressure — capable of filling a classroom or small restaurant or bar with enough volume so everyone can clearly hear. A pair of EON 315s working together in a larger PA system can play loud rock 'n roll in those small venues, or amplify softer programming in larger rooms and auditoriums.

You'll dramatically increase your music's impact and volume when you combine a couple of EON 315s with a matching EON 518S powered subwoofer or two. Each added sub takes over all the heavy work associated with reproducing bass, so the EON 315 can play the rest of the sound that much louder.

How loud do powered PA speakers play?

If you're considering powered speakers, you might be tempted to compare wattage ratings, but those won't be very helpful to you: these self-contained systems are engineered to precisely match their built-in amps with their speakers in order to get the most output possible. We suggest you pay more attention to the listed sound pressure level (SPL) ratings than the listed wattage ratings.
These boxes are all designed to play loud and clear in appropriately matched room sizes. Generally, powered PA speakers work best in small to medium venues, like nightclubs, coffeehouses, and small auditoriums. If you're performing in larger venues, you'll probably need separate power amps and speakers.

Features

Powered PA Speaker: The EON315 is a two-way, powered, portable speaker.
The EON315 is comprised of a 15" JBL woofer with 2.5" ribbon voice coil and a 1"
throat neodymium high-frequency compression driver coupled to a 100° (h) by 60°
(v) waveguide. Both speaker components are driven by the discrete channels of a
280 watt Class-D integrated power amplifier.

Rugged Bass Reflex Enclosure: The JBL EON315 features a
highly designed composite enclosure for durability, lightweight, and acoustic
performance. A bass reflex port provides greater efficiency and bigger bass
output. A full screen-backed steel grille offers additional protection for both
the woofer and compression driver components.

Inputs/Outputs: A combo-connector offers XLR and 1/4" TRS phone jack
compatibility. Selectable input sensitivities allow a broad range of devices to
be properly matched, from the output of a mixer to an MP3 player or a dynamic
microphone. A balanced XLR loop through output connector enables the simple
"daisy-chaining" of additional EON powered speaker if more coverage and level is
required.

EQ Settings: Pre-engineered selectable system EQ is provided to assist
in optimizing the system to your source material and acoustic environment. 3 EQ
presets are provided.

Flat: The "Flat" setting is ideal for live music. This is a
neutral setting with no extra EQ applied and should be utilized in most
typical PA applications. The frequency response is flat, linear, and
unaltered. In this setting more level will be achievable at the maximum
performance limits of the speaker.

Boost: The "Boost" setting is used for reproducing low level
pre-recorded music, delivering extra low and high frequency energy. When the
control is switched to the Boost setting, low frequency and high frequency
equalization is applied; +3dB shelving filter at 150Hz and +2.5dB shelving
filter at 4kHz. With the Boost applied, love level music playback will sound
much fuller with increased high frequency clarity.

Cut: In the "Cut" position, maximum level can be achieved for
speech reproduction by reducing need to reinforce the lower frequencies.
This is also a typical setting when using the system as a floor monitor,
reducing low frequency build-up which occurs naturally when placed on a
floor. Low frequencies (120Hz) are cut (-6dB) from the systems response.
This position should be selected when the speaker is used with a subwoofer,
for speech reproduction, or as a floor monitor.

Integrated Carry Handles: Three full size handles provide
the carrying flexibility required of a highly portable speaker system, whether
sliding it onto the back seat of a car or lifting it up to place on a stand.

LED Indicators: The EON315 features two LEDs to indicate the speaker's
status.

Signal: The Signal LED (Green) illuminates to indicate a usable
audio signal is present at the speaker's connected input.

Limit: The Limit LED (Red) illuminates to indicate that the
system is approaching clipping. The threshold for this is actually about 2dB
below clipping. An occasional flickering of this on the loudest peaks is
acceptable. If this LED is on for more that the duration of brief dynamic
peaks, the speaker is being over-driven.

Applications: The JBL EON315 PA speaker is great for live sound
reinforcement, speech and vocals, music playback in entertainment, A/V, and
institutional venues; especially when ease of use and portability are important
factors. Plus the EON315 can be used for amplification, mixing, and monitoring
of musical instruments.

Mounting Options: The universal mounting capabilities make the EON315
perfect for live performers, fixed installations, or commercial A/V rental
companies. Whether you use the speaker on a tripod stand (36mm socket), mounted
on a subwoofer with a pole, in the floor monitor position, or in a fixed
position suspended by the M10 points, you can count on superior and reliable
performance.

Placement Recommendations: The following guidelines will help you
achieve optimum sound wherever you use your EON loudspeakers.

Raise Speakers: For best results try to get the high frequency
horn at least 2-4' above the heads of the audience. If the speakers are too
low, the people in the back of the audience will not receive the best
quality sound.

Place Speakers Between the Mics & Audience: Feedback occurs
when the microphones pick up sound from the speakers and "feed" the sound
back through
the sound system. If space is limited, point the speakers away from the
microphones to reduce feedback.

Locate Speakers Away From Turntables: Low-frequency
feedback occurs when the output of the speaker is picked up by the tone arm
of the turntable
and is re-amplified. A heavy, solid turntable base and shock mounting can
also reduce this type of feedback in DJ applications.

Use More Speakers in Large or Highly Reverberant Spaces:
Spreading speakers throughout these spaces will produce much better sound
than trying to compensate with loudness level or equalization. For very long
distances, the use of another set of speakers with time delay is
recommended.

Stand Speakers Upright for PA/Tilt the Speakers Stage Monitoring:
Upright stance provides even coverage over a wide area. EON speakers are
also designed with two slanted positions for stage monitoring applications.
